I took the time and effort to learn from ENTs - Ear, Nose & Throat Doctors, top vocal coaches, and to study music from industry pros (I've written over 2000 songs), anatomy, acoustics and vocal technique to know what is on the test below:

TEST YOUR VOCAL COACH

Some vocal coaches might say, "You don't have to know any of that to be a vocal coach." The truth is that you don't have to know anything at all to call yourself a vocal coach. How effective you are, is proportionate to what you know and what you can do. A vocal coach can choose to know nothing about anatomy, physics, musical style, or whatever else.

I thought it was a good idea to consult with true experts, such as physicians. I studied arranging with working professionals. I drew the plans for the mixing room at NBC Burbank, where The Tonight Show was filmed. I have been tested on my knowledge of acoustics and passed the test.

If you are a vocal coach (or a singing teacher) and you are in it just for the money, maybe it's time to make a choice: learn what you need to know to do your best work or leave the profession and make room for those who truly care about singers and about singing as an art. Some of the questions are "trick questions" , but they are based on outdated and/or incorrect "myths" regarding anatomy, muscle function, and physics.
